. Be it'kwnownn thatI, JAMES R. BABCOCK, a

` citizen of theUnited States, lresiding at Fort Mio Pierre,"inthefcfounty f Stanley and State of South Dakota, have invented certain new and useful.Improvements in Wheeled Plows or Oultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in wheeled plows or oultivators of the gang-plow type; and its objectsare to provide improved,

ments of parts, as will f; be hereinafter more fully described, and particularly pointed out' in the appended claims.

In the accompanying drawingsyFigure 1? is` a side elevational view ofa gang plow or cultivator embodying my invention. Fig. 2is

a top plan view of the same. Fig.` 3 is a front end elevation. Fig. 4 is arear end elevation. Fig. 5 is a vertical transverse section taken `on line 5 5 of Fig. 2. Fig. 6 isa cross-section through the ratchet-hub of the drive-gears,

looking toward the coperating tractionwheel and showing the pawls or dogs engaging therewith.

Referring now more particularly to the drawings, wherein like referencemumerals designate corresponding parts throughout the severalviews, the numeral 1 designates the frame ofthe plow or cultivator, which is rectangular in form` and comprises in its construction two sidebeams 2,a front cross-bar 3, a rear cross-bar 4, andan arched bar 5.

The forward end of/the frame is supported. by a caster-wheel 6,`mounted `upon thefront.`

cross-bar 3, and to said bar draft appliances are connected in practice for the attachment of draft-animals.

The rear portion` of the frame is supported by traction-wheels 7, which are mounted upon stub-shafts 8,forn1ed integrally with or fixed to pendent extensions A the side beams, and are preferably spurred `or studded in the usual way to prevent slipping and to increase their hold upon the sur face of the ground. Hingedat their forward ends to studs projecting from the arched bar 5 are a Series of spaced parallel guide-bars 10, having their rear ends connected by a slat Slidably vmount-ed in these Ways are a series of cross-heads 13, (four in number,) to `which are attached a corresponding number of pitman-rods 14, connected at their forward ends to cranks 15, formed upon acrank-shaft 16, journaled in bearings 17, said cranks being arranged to project radially equidistant around the circumference of the shaft, so as to come into operation in turn at each quarter-revolution of the shaft. Through the said cross-heads project standards 17-L of plow-shovels 20. These standards are made vertically adjustable in said cross-heads by any suitable means-for instance, by forming the standards with a vertical row of aper- V tures through which pins are adapted to be inserted. The plows are successively thrown yor thrust forwardly through the soil by the movement of the crank-shaft ina manner readily understood. Alever 21 is pivotedt'o" a suitably-secured cross-bar 21a and is connected by a rod 22 with one of the guide-bars 10 and is adapted to be moved in one direction or the other to raise or depress said bar, so as to adjust the plow-Shovels for deep or shallow plowing. This lever is provided with a pawl 22', adapted to engage a Segmentrack 23 to hold the lever fixed in adjusted position.

The crank-shaft is operated to reciprocate the pitman-rods by means of the following mechanism: 24 represents a drive-shaft j ournaled in lthe side beams and carrying near'one end a spur-gear 29', which meshes with a pinion 26 on a counter-shaft 27, which countershaft is provided with crank-arn1s`28, which are connected to the ends of the crank-shaft .through the medium of connectingrods 29, whereby power is communicated to said crank-shaft. The gear 29 is loosely mounted on the shaft 24 and is provided with a clutchcollar 30, adapted to be engaged bya sliding sleeve 31, notched to engage pins 32 on said shaft, whereby the gear may be thrown into IOO and ont of operation. Alever or shipper-bar 33 is provided to operate said sleeve 3l. The drive-shaft 24 also carries at its ends pinions 25, which mesh with drive-gears 34, mounted on the stub-shafts 8 npon the inner side of the traction-wheels 7. These drive-gears are provided with ratchet hubs 35. Springpressed pawls 36 are carried by the tractionwh'eels to engage said ratchethubs and rotate the gears in a forward direction to impart movement to the drive mechanism and to slip loosely over the ratchet-teeth upon the rearward movement ofthe traction-wheels, as when backing the plow, without operating the drive mechanism.

Having thus fully described my invention, A what I claim, and desire to secure by Letters Patent, is-

l. In a gang plow or eultivator, the combination of plow-shovels, pitman rods connected thereto, a crank-shaft for operating the pitman-rods, drive-gears having ratchets, traction-wheels carrying pawls to engage said ratchets, and gearing between the drive-gears and pitinan-rods, substantially as set forth.

2. In a gang plow orv cultivator, the combination of a Wheel-supported frame provided with longitudinal guide-bars, a crank-shaft 'esima geared with the spprtigwheels, cross"- headsl mounted to slide on said guide-bars, pitmen connecting the cross-heads with the crank-shaft, and shovels having their standards connected to the cross-heads, substantially as set forth.

3.` In a gang plow or' cultivator, the combination of a Wheel-supported frame provided with longitudinal hinged guide-bars, a crankshaft geared with the supporting wheels, cross-heads mounted to slide on said guidebars, pitrnen connecting the cross-heads with the crank-shaft, shovels having their standards connected to the cross-heads, and means for elevating the said hinged guide-bars, sub; stantially as set forth. v Y

4. 4In combination, a main frame and a suitably-mounted gang of plows, and means for forcing'them successively forward with respect to the main frame, substantially as del scribed.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit-
